To all whom it may concern:

Be it known that I, JOSEPH LnnwntK a citizen of the United States, residin at Philadelphia, county of Philadelphia, l tatc of Pennsylvania, have made a certain new and u'seful Invention in Sheet-Metal Wheels, of which the following is a specification.

This invention relates to sheet -metal wheels.

The object of the invention is to provide a construction of sheet metal wheel Which is simple in structure, strong, durable and economical to manufacture.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafterset forth, as shown in the accompanying drawing, and finally pointed out in the appended claims.

, In the drawing, Figure 1 is a view in perspective, parts broken off and parts in. sect1on showing a structure of sheet metal wheel embodying the principles of my invention.

Fig. 2 is a broken detail view in section on the line 2,2, Fig. 1, looking in the direction of the arrows, and showing the manner of connecting the spoke ends to the rim or felly structure.

In carrying out my invention a sheet of steel is stamped or cut to the required shape and dimensions to form the hub sleeve and spokes, the latter being formed by slitting the opposite edges of'the stamping. The stampingis then rolled into tubular form with the meetingends of the portion to form the hub slee've suitably secured together.

The portions of the stamping formed by slitting the edges thereof are then bent out radially from the ends of the hub sleeve to form the wheel spokes integral with the hub sleeve. These operations are exceedingly simple and easily and expeditiously accomplished.

In the drawing 1 designates the tubular hub sleeveportion and G, the-spokes which are integral therewith, in a sheet wheel structure produced as above described. In practice, and in order to secure additional strength I prefer to form the spokes with solar ed outer or free ends, as indicated at H. re free ends H of the spokes are applied against and suitably secured, as by welding, to the sides D of a ring. shaped sheet metal stampin B of channelv shape in cross section with ateral flanges C. The channel of this member presents outwardly. A rim member A of any desired type or form is applied to and secured against the radially outer surfaces of the lateral flanges C of the stamping B. I have shown a standard form of clencher rim' A, but my nvention is not to be limited or restricted in this respect as other forms and typeslof run are applicable for use in connection with my invention with equal facility and advantage. The rim member A, whatever its form or typeis secured by welding or otherwise against the radially outerSurfaces of the lateral flanges C of the channel stamping B.

If desired, and in order to conceal the spoke ends and present a neat finished appearance, as well as to add strength and rigidity to the telly structure sheet metal ring stampiugs E are applied against the sides of the spoke ends, and welded or otherwise secured thereto. In this case it may sometimes be preferable to form oli-set or depressed seats .I in the ring stampiugs E, to receive the sides of the spoke ends so that the portions K of the ring slampings intel-mediate adjacent spokes will lie against and may be welded or otherwise secured to the sides I) of the channel stamping B, thus forming a very strong and rugged but cheap and economical telly structure which is of neat and finished appearance.

It will be understood, of course, that the set oi spokes G at one end of the hub sleeve .1 will be applied and secured to one side of the channel stamping B, while the set of spokes at the other end of the hub willbe applied and secured to the other side of the channel stamping.

It will be seen that all the parts eoin posing the wheel and telly structure are of simple shape capable of being readily. easily and quickly formed of sheet steel stampings with great economy of material and labor, and he assembly operations are equally simple and can be aecon'iplished expeditiously and economically, thus resulting in the productionof a strong durable and eilicient sheet metal wheel for use on automol'iiles or other vehicles with a minimum of cost of manufacture.

Various changes in the details of structure, arrangement and relation ol parts-will readily occur in persons skilled in the art. and still fall within the spirit and scope of my invention. 1 do not desire, therefore, to be limited or restricted to the exact details shown and described. 7

But having now set forth the object and nature of my invention, and a structure em bodying the principles thereof, what i claim as new and useful, and ol my own invention,

and desire to secure by laitlxirsPateiit, is

'1. In a sheet metal Wheel, a hub sleeve portion. having integral spokes at the respective ends thereof, in combination with a ring of U-shape in cross section, the channel of said ring presenting outwardly, the

- outer orfree ends oi thespokes being a of the spokes plied flatwise against and secured to tie outer radial side surfaces of said channel ring, and a rim member secured to the outer periphery of said channel ring.

2. In a shiaatmetal wheel, a hub sleeve portion having integral spokes at the ends thereof, in cinnbination with an outwardly presenting channel ilHBltIllW/l' having,- lateral edge flanges, the Free ends of the spokes at'the opposite ends of the hub sleeves, respectively, being applied against and secured to the respective sides of said channel member, and abutting endwise against the and a rim member applied against and secured to the outersurfaces of said flanges. v 8. In a sheet metal wheel, a hub sleeve portion having, integral spokes at the ends therei of, in conrbinat thereof presenting outwardly, the outer free ends of the spokes being applied against and secured to the sides of said channel shaped stamping, and a rim nreniber applied against and serured to the radially outer surface of said channel stamping.

4. In a sheet metal wheel, al ul) sleeve portion having integral spokes at the ends thereof, in combination with an outwardly pre senting channel shaped l'elly stamping to the respective sides oi which the outer ends are applied and secured, ring; stampings applied against the outer side surfaces of the spoke ends to conceal the mner surfaces of said lateral edge flanges,

ion with a ring stamping of of the 'channel shape in cross-section the channel applied and secured, ring stampings applied against the outer side surfaces of the folly stamping and over the sides oi. the spoke ends to conceal the latter, said ring stampings having off-sets or depressions forming, seats to receive the spoke ends, and a rim member ,applied against'and secured to the radially outer surface of the folly stampmg.

6. In a sheet metal wheel a hub sleeve portion having integral flat spokes at, the ends thereof, said spokes havingtl'ieir Gilt/0P0! free ends extended in the direction of the width thereof, in combination with a rim, stamping of channel shape in cross section, the channel thereof opening radially outwardly, said stamping having laterally cX- tending edge litii'lgt'tfs the extended free ends of the spokes being applied flatwise against and secured to the respective sides of said stamping, and a rim member applied against and secured to the radially outensurfaces ot'said flanges.

7, In a sheet metal wheel a hub sleeve portion havingintegral flat spokes at the ends thereof, said spokes having their outer or free ends extended in the direction of the width thereof, in coinbination with a ring stamping of channel shape in 'cross section, the channel thereof opening radially outwardly, said stamping having tending edgeilanges, the extendedfree ends spokes being applied t'latwise against and secured to the respective sides of said stamping, ring stampings applied against the outer sides of the enlarged spoke ends to conceal the latter, and a rim member applied against. and secured to the radially outer surfaces oi said flanges.

laterally cX-' In testimony whereof- I have hereunto set my hand in the presence ol' the subscribing witnesses, on this 18th day ol February A, l)., 1917. I
